Doo-R CONSTRUCTION FOR LAMPS AND THE LIKE.

Application filed' July 13,

This invention relates to a door construe# tion and particularly to meansv for holding' a door as the door or a'lamp casing. or similar doors as port lights, tightly closed'so that they are weather tight and whereby the door can be opened and swings entirely out of therway. f

The invention consists inthe novel ieatures and in the combina-tionsl and construe'-r tions hereinafter set forth'andclaimed.

In describing this invention, reference. is had to the accompanying drawing in which like charactersy designate corresponding parts in all ythe" views.V

My door construction is here shown'as embodied in a lamp `construction or applied to a lamp casing or box and in the drawing,

. Figure l, is an elevation of a door embodying one form of lmyinvention, the contiguous part of a lampv casing to which the door is applied and also the doors on the othersides of the casingbeing also shown;

. Figure 2 is a fragmentary elevation of the door embodying another form ot' thisr 1nvention. s

Figure 3y is raview similar to Figure 2 ot still anotherform'of this invention.

This door construction, comprises generally, abody or box having a door opening,v

a pluralityof studs, preferably more than two, spaced apart around'the door opening and preferably in afcircle struck from the center of thedoor opening, the studs having heads attheir outer ends, a door provided with outwardpro'jections ormediwith slots extending in the general direction iof an arc struckv from the center of the door, these -slots being open at like-ends, anv additional means provided with a slot located at the rim of the door for receivingnanother of the studs, this slot also extending in a general directionof an arc struck from the center of the door.

1 designates the body which is .here shown cubical in form and having door openings 2 on a plurality of sides thereof and a door for each opening. The doors are all alike in construction.

3 designates each of the doors which include a frame or rim in which a glass or lens 4 is mounted in any suitable manner.

The openings 2 of the door are usually round or circular and also the rims of the door 3 are'correspondingly circular.

5 are the studs spaced apart around the i926. seriai No; 122,235.

as tour in number spaced'equidistance apart. i

The rim or frame of the door 3 is provided with outward projections as lugs 6 having open ended slots 7 therein, these slots extending in the general direction of an arc of a' circle struck from the lcenter of the'l door or of the' door opening, the slots being open. at like ends so that the lugs are practically hooks. As here shown, there are three hook shaped lugs 6.

The door is also provided with means" formed with an additional slot'S` for receiv ing the fourth stud 5, this slot S also extending in the general direction of the arc of saidv circle andhavin'g an enlargement 9 at one end The slot may be providedin a'l hinge block as 10 having trunnions 11 at'its ends hinged to projections or `lugs"12 extending' outwardly from" the rim Aof `the door 3, the axes ofthe trunnions extend in a chord or the arc or said circle; or as'seen'in Figure' 2, the slot 13 correspon-ding to the slot*8 may be provided directly inthe lug 14 instead of in the block.` Also, as seen in Figure 3, the slot 15 corresponding to the slot 8 `may be formed without the enlargement 9.

The studs 5 are here shown as wing'screws threading into holesin the body.'4 I

In operation, the' wingscrews are normally tightened holding the door snugly in closed position.l Toopen the door all thev Wing screwsyare loosened and then thedoor given a slight turn aboutits axis to move the lugs 6 ou't of engagement with the wing screws orJ studs 5, this movement also movingthe slot 8 along the remaining wing screw 5 so that thedoor can now be swung outwardly and laterally, the outward swinging permitting the lugs 6r to clear the wing screws. This'outward swingingis permitted by the hinge block 10 or by the enlargement 9 of the slot 8 or 13 without requiring much loosening movement on the part of the wing screws 5. To close the door, the reverse of these movements takes place.

This door construction is particularly advantageous in that the door is held snugly in closed position and can be opened with very little loosening movement of the Wing screws.

What I claim is:

1. In a door construction, the combination or a body having a door opening, a plurality of studs spaced apart in a circle around the door opening, a door provided with outwardly projecting lugs formed with open ended slots for receiving all but one of the studs and an additional lug formed with a slot provided with lan enlargement, said studs being screws threading in the body through the slots.

2. In a door construction, the combination of a body having a door opening, a plurality of studs spaced apart in a circle around the opening and having.heads at their outer ends, a door provided with a plurality of outwardly projecting lugs formed with open .ended slots extending in the direction of an arc of a circle struck from the center of the door, for receiving all but one of the studs and the door being provided with means formed with a slot extending in the arc of such circle for receiving the remaining stud.

3. In a door construction, the combination of a body having a door opening, a plurality of studs spaced apart in a circle around the opening and having heads at their outer ends, a door provided with a plurality oi' outwardly projecting lugs formed with open ended slots extending in the direction of an arc of a circle struclr` from the center oi the door for receiving all but one of thev studs and the door being provided with means formed with a -slot extending in the arc of such circle for receiving the remaining stud, the slot being provided with an enlargement at one end.

4. In a door construction, the combination of a body having a door opening, a plurality of studs spaced apart in a circle around the opening and having heads at their outer ends, a door provided with a plurality of outwardly projecting lugs formed with open ended slots extending in the direction'of an arc oi a circle struckfrom the center of the door for receiving all but one of the studs and the `door being provided with means formed with a slot extending in the arc of such circle for receiving one of the studs, the studs being screws threading into the body through the slots with their heads overlying the lugs and said slotted means.4

5. In a door construction, the combinaa tion of a body having a door opening, a" plurality o'l'studs spaced apart around the door opening having heads at their outer ends, a door provided with outwardly projecting lugs formed with slots extending in the general direction of an arc struck from the center of the door, the door being also provided with outwardly projecting means formed with a slot extending in the general direction of such arc for receiving one of the studs, said means comprising a hinge block formed with said slot and hinged to the door on an axis extending in the direction of a chord of such arc. i

6. In a door construction, the combination of a body having a door opening, a plurality of studs spaced apart around the door opening having heads at their outer ends, a door provided with outwardly projecting lugs formed with slots extending in the general direction of an arc struck from the center of the door, the door being also provided with outwardl projecting means formed with a slot extendSi ing in the general direction of such are for receiving one of the studs, said means compris# ing a hinge block formed with said Slotand hinged to the door on an axis extending in the direction of a chord of such arc, the slot in the hinged block being provided with an enlargement.

7. In a door construction, the combination of a body having a door opening, a plurality of studs spaced apart around the door opening having headsat their outer ends, a door provided with outwardly projecting lugs formed with slots extending in the general l direction of an arc struck from the center of the door, the door being also provided with outwardly projecting means formed with a slot extending in the general direction of lsuch arc for receiving one of the studs, said means comprising a hinge blockV formed with said slot and hinged to the door on an axis extending in the direction of a chord of such arc, the studs being clamping screws threading into the body through the slots and having the heads overlying the lugs and the hinge block. l

` In testimony whereof, I have hereunto signed my name, at Syracuse, in the county of Onondaga, and State of New York, this 26th day of June, 1926.
